Surface Area and Lateral Area of Triangular Prisms

The video tutorial explains how to calculate the surface area of a triangular prism. It begins by defining the surface area components: lateral area and base areas. The lateral area is calculated by finding the perimeter of the base and multiplying it by the height of the prism. The base areas are determined using the formula for the area of a triangle. Finally, the total surface area is obtained by adding the lateral area and the areas of the two bases.

What is the first step in finding the surface area of a triangular prism?

• Find the lateral area

• Calculate the volume

• Measure the angles

• Determine the height
